An improved streaming of a Virtual Reality [VR] video to a VR rendering device is provided. The VR video may be represented by a plurality of streams each associated with a different view of a scene. A view of the scene may be determined which is to be rendered by the VR rendering device. A subset of streams may be identified which is needed to render the view of the scene. The streaming of the subset of streams to the VR rendering device may be effected by streaming the plurality of streams from a stream source to a forwarding node downstream of the stream sources and upstream of the VR rendering device, and selectively forwarding the subset of streams from the forwarding node to the VR rendering device in response to the view having to be rendered by the VR rendering device. As such, the switching latency between streams may be reduced. Namely, streams which are not needed for rendering a current view, but which may be needed for rendering a next view, may be continuously made available at network nodes nearby the VR rendering device.

Streaming virtual reality video

One aspect of the disclosure relates to a method for providing a service to a user equipment connected to a first operator network. The second operator network comprises a register containing subscription information of the user equipment. The method comprises a number of steps. One of these steps is receiving from the first operator network a service request of the user equipment, the service request being associated with the service. Another step is obtaining a service-deployment-specification for the second operator network comprising at least one network function associated with the service on the basis of the service request. Yet another step is converting the service-deployment-specification for the second operator network into a generic specification, the generic specification enabling execution of the at least one network function in the first operator network for providing the service to the user equipment. Yet another step is transmitting the generic specification to the first operator network. The invention further relates to systems and nodes in the first and second operator network, and to a computer program product for performing methods for providing the service.
